ISO 19115 Geographic Metadata Information


NASA's Earth Science Division (ESD) International Organization for Standardization (ISO) 19115 Geographic Metadata Standard - Implementation Requirement and Guidance document describes the ESD-approved implementation guidelines for required metadata to be included in science data products. The metadata requirements represented in this document provide a means of assuring the consistency of data requirements across subsystems and supporting the data standardization necessary for system interoperability. The document lists the relevant ISO standards to be used to describe science data products. Complete descriptions of NASA collections and products will require elements from all of these ISO standards.

Links to the ISO Implementation Requirement and Guidance document, user resources for ISO metadata, NASA's Common Metadata Repository (CMR), and NASA's Unified Metadata Model (UMM) on which CMR is based, are provided below. NASA conventions and best practices using ISO 19115 are currently under development, but a wealth of user resources are available.


ISO 19115 implementation guidelines were approved for use in NASA's Earth Science Data Systems and published here in December 2014. The current document, ISO 19115 Geographic Metadata Standard - Implementation Requirement and Guidance, was approved in July 2018. This document is maintained by the ESDIS Standards Coordination Office (ESCO), and is under configuration control in the Configuration Management EOSDIS Tool (COMET).

NASA ESDIS Unified Metadata Model (UMM): The Unified Metadata Model (UMM) encompasses various metadata profiles maintained and archived by EOSDIS, including ISO 19115, and is used by the CMR to drive search and retrieval of metadata cataloged within that system. UMM profiles are not metadata standards.
